Glucose
Facts:
-Is a Hexase sugar (six carbon bonds)
-Has 2 forms, Alpha α and Beta β

Uses:
-Plants making cellulose
-Active transport
-Energy-passed via foodchains
-Respiration
(Can be converted into Glycogen used when exercising)

Key Words:
Alpha and Beta Glucose
Water
Disaccharide
Condensation Reaction (forms water)
Covalent Bonding
Glycosidic Bonds

Equation=
Photosynthesis Equation=

-Form of Carbohydrate-a family of molecules (atoms of carbon and components of water)
-Glucose is a monomer that makes up starch

Structure:
-6 carbons, 12 hydrogens and 6 Oxygens
-As a dry powder it has a straight chain form
-When dissolved in water, chains form into ring structures (2 different forms of ring for both alpha and beta)
-carbon atoms numbered clockwise from oxygen atom (represented with circle)
-Alpha and Beta glucose make polysaccharides which have different properties
